Find the coordinates of point B along a directed line segment from A(3,4) and C(3,9) so that the ratio o
to BC is 4:1.

Point B is (3, 8)

Step-by-step explanation:

Hello, Jacky,

Note that points A and C have the same x-coordinate and thus lie on the same vertical line, which is x = 3.  To determine the length of this directed line segment, we need only subtract 4 from 9, obtaining 5.

Now if we start at (3,4), move up 4 units along this vertical line, plot a point there, and finally move 1 more unit along this line to C(3, 9), we will have partitioned the line in the ratio 4:1.  To find the coordinates of this point, we simply take x = 3 (see above) and add 4 to y = 4), obtaining the point (3, 8).  This is Point B.

Point B is (3, 8)

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.

i googled it and this is what i got i don't know how it is. sorry.
